| Abstract: | We present a film composed by bromocresol green (BCG) dye and resin mixed with isopropyl alcohol as photosensitive emulsion. In this film, we have recorded phase gratings with the emission line λ = 457 nm of an argon laser. The characterization of this film indicates us a diffraction efficiency of 2.27%; and its simple fabrication and low cost make this film an attractive option for holographic elements. |
